3) main hook, secondary hook are hooked on firmly hook respectively and hang position, main hook push and block plate is promoted to rotate clockwise with the lower end of the movable hook body of main hook again, under the resilient force of the hook lock pin return spring of main hook, the hook look of the main hook movable lower end of hook body that only horizontal pin termination puts in main hook makes the fixed hook of main hook and Removable hook link into an integrated entity; Start stop lever under another lower side pressure of main hook push and block plate, the lower starting switch of the lower end cross bar pressure of start stop lever starts wireless transmission device and telltale; Then secondary hook push and block plate is promoted to rotate clockwise with the lower end of movable hook body of secondary hook, under the effect of the hook lock pin return spring of pair hook, the hook look of the secondary hook movable lower end of hook body that only horizontal pin termination puts in secondary hook makes the fixed hook of secondary hook and Removable hook link into an integrated entity; Warnings is cried in telltale ring, and only horizontal pin and the secondary hook look linked up with stop horizontal pin and all not yet lock the hook look of display main hook;
4) main hook trip switch and secondary hook trip switch is pressed respectively, the solenoid of hook lock pin control device obtains electric generation magnetic force and attracts lock pin body, lock pin body overcomes the elastic force of lock pin body return spring, put in the cross-drilled hole pinning hook look only horizontal pin that hook look stops horizontal pin one end, telltale stop ring, display main hook and secondary hook are all in the lock state;
5) when needing mobile main hook, again press main hook trip switch, the hook lock pin control device of main hook unlocks, solenoid dead electricity magnetic force disappears, lock pin body departs from the cross-drilled hole that hook look stops horizontal pin one end under the resilient force of lock pin body return spring, and the hook look of the main hook that can extract is horizontal pin only; Start stop lever rises under start stop lever return spring resilient force, and starting switch cuts out, and wireless transmission device and wireless receptor are all in closing condition; When guaranteeing that main hook unlocks, the hook look of secondary hook stops horizontal pin and is still in the lock state; Then the Removable hook opening main hook takes off main hook;
6) when needing moving sets to link up with, again press secondary hook trip switch, the hook lock pin control device of secondary hook unlocks, solenoid dead electricity magnetic force disappears, lock pin body departs from the cross-drilled hole that hook look stops horizontal pin one end under the resilient force power of lock pin body return spring, the hook look only horizontal pin of the secondary hook that can extract; The solenoid of main hook remains on to obtain electricity condition simultaneously, the hook look only horizontal pin of lock pin body locking main hook;
7) repeating step 3)��4), hook hangs up properly main hook or secondary hook again;
8) complete working aloft, it is necessary to when taking off main hook and secondary hook, repeating step 5)��6) after, the power switch pressed on main hook electric control gear is cut off the electricity supply, telltale stop ring; Main hook and secondary hook unlock, and extract corresponding hook look only horizontal pin respectively, take off main hook and secondary hook, and ribbon is incorporated into and knits in Webbing retractor simultaneously.
